Mercury Rx makes an inferior conjunction to the Sun on September 12th, at 20 degrees Virgo. This will be a moment of clarity, as something in need of review or correction is illuminated. We're at the halfway point of the Mercury Rx cycle, so you should have gathered some information by now. Use this moment to make sense of things.
Mars in Sagittarius will square Mercury on September 12th, and the Sun on September 13th. Mars will trigger aggravations, arguments or an impatient push to get it right. If Mercury Rx has delayed progress or sent you mixed messages, September 12th to 13th can be a turning point. You won't move forward just yet, but the remaining details will come tumbling out. Anger may be the clarifier. Or, you may be motivated to finally tackle an issue you've been avoiding.
If a key person makes an appearance, or reaches out from the past, consider them to be a catalyst. The disruption they bring is designed to draw your attention to a very specific detail. What do you need to refine? What do you need to get real about? What facts have you been ignoring?
Mercury's conjunctions with the Sun are part of a unique cycle (a synodic cycle). An inferior conjunction between Mercury Rx and the Sun is the start of a new cycle, although each conjunction (a point of clarity, new information) is connected to the next. The last conjunction happened on July 6th at 15 degrees Cancer. The next conjunction (after Virgo) will be on October 27th at 4 degrees Scorpio. July 6th may be connected to what happens on September 12th, and what you learn on September 12th may inform events on October 27th.
